7.Massive buildings as mast part, flip capable, prime kit and hoisting jib undertake sophisticated tools as NC machine instrument, drilling equipment, milling device processing right after welding. That properly guarantees merchandise assembly precision, lowering the failure rate and strengthening the security.


8.twelve automated spraying assembly line, the whole equipment adopt impeller blasting to make sure the cleanliness of metal surface area and eliminate the inner pressure producing in welding approach, improve the energy and metal surface hardness, enhance portray adhesion. Two primer, a paint spraying technologies, stunning look, corrosion resistance has elevated far more than two times than the daily life of normal spraying method. System, the tiny car, fence and other tiny parts adopt hot dip galvanized following acid phosphate remedy, rust resistance more robust.


9.Hoisting, derric ept and slewing mechanism, with comprehensive protection this kind of as torque, fat restrict. The steel wire rope damaged rope unit. Assortment of the automobile design and style from loss and damaged shaft, this kind of as tilting system. The electricalWhen the torque load exceeds the rating of its precision tempered torque springs, the Torq-Tender’s push key pivots out of the engagement slot to disengage the system. When disengaged, the torque limiter does not offer considerable resistance to rotation. adopts overload protection, the design of PLC self-diagnosis technique, it really is hassle-free to maintenance.
